Answer 1

B.) Enter the net ionic equation representing aqueous acetic acid neutralized by aqueous barium hydroxide.

Answer: CH₃COOH (aq) + OH- (aq) ------> CH₃COO^-(aq) + H₂O(l)

Since acetic acid is a weak acid, it must appear in the equation, not just as H+. Barium hydroxide is a strong base, so the barium is a spectator.

C.) Enter the molecular equation representing solid chromium (III) hydroxide reacting with nitrous acid.

Answer: Cr(OH)₃(s) + 3HNO₂(aq) → Cr(NO₂)₃(aq) + 3H₂O(l)

D.) Enter the net ionic equation representing solid chromium (III) hydroxide reacting with nitrous acid. Nitrite is soluble.

Answer: Cr(OH)₃(s) + 3HNO₂(aq) → Cr³⁺(aq) + 3NO₂⁻(aq) + 3H₂O(l)

E.) Enter the molecular equation representing aqueous nitric acid and aqueous ammonia reacting.

Answer: HNO₃(aq) + NH₃(aq) --> NH₄NO₃(aq)

F.) Enter the net ionic equation representing aqueous nitric acid and aqueous ammonia reacting. Nitrate ion is spectator ion.

Answer: H⁺(aq) + NH₃(aq) --> NH₄⁺(aq)

during net ionic equation expression spectator ions (OR common aq ions at both sides should omit)
